Hi Experts,

I have one requirement where i have to add additional characteristic for results recording.

My question is where should i add?

1. At the time of production order creation and released, number is assign to Inspection lot but not able to add addition Insp characteristic Once the order is save, we can add characteristic in change mode of order.

How to add extra characteristic at order creation or rel or at the time of savings.

2. Is it possible to add characteristic automatic while results recording with some condition. If Yes, How? and when it can be added

User don't want to add the characteristic manually at any stage from Order creation to result recording screen.

I am trying with Enhancement -QEEV0002, it is not taking.
